in wood, metal, ceramic and plastic
as well as for screwdriving
Vario-Lock position for adjust-
ment of the chiselling position The
mode selector switch does not latch
in this position.
Position for chiselling
Reversing the rotational direction
The rotational direction switch is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch actuated.
Switching On and Off
To start the machine, press the On/Off switch.
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button.
To switch off the machine, release the On/
Off switch. When the On/Off switch is locked,
press it fi rst and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on
power tool can be variably adjusted, depend-
ing on how far the On/Off switch is pressed.
Light pressure on the On/Off switch results in
low speed/impact rate. Further pressure on
the switch increases the speed/impact rate.
Overload Clutch
► If the tool insert becomes caught or
jammed, the drive to the drill spindle is
interrupted. Because of the forces that
occur, always hold the power tool firmly
with both hands and provide for a secure
stance.
► If the power tool jams, switch the ma-
chine off and loosen the tool insert.
When switching the machine on with the
drilling tool jammed, high reaction torques
can occur.
Working Advice
► Before any work on the machine itself,
pull the mains plug.
Changing the Chiselling Position (Vario-Lock)
- Changing the Chiselling Position (Vario-
Lock)
- The chisel can be locked in diifrent posi-
tions. In this manner, the optimum working
position can be set for each application.
- Insert the chisel into the tool holder.
- Turn the mode selector switch to the
“Vario-Lock” position.
- Insert the tool in a twisting manner into the
tool holder until it latches itself.
- Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a
certain radial run-out at no-load,
which has no eff ect on the accuracy of the drill
hole, as the drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools (see fi g-
ure D)
- Push back the locking sleeve and remove
the tool.
Dust Extraction with the Dust Extraction
Attachment
► Dust from materials such as lead-con-
taining coatings, some wood types,
minerals and metal can be harmful to
one’s health. Touching or breathing-in the
dust can cause allergic reactions and/or
lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust,
is considered carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
- As far as possible, use a dust extraction
system suitable for the material.
- Provide for good ventilation of the working
place.
- It is recommended to wear a P2 fi lter-class
respirator.
Observe the relevant regulations in your
country for the materials to be worked.
► Prevent dust accumulation at the work-
place. Dust can easily ignite.
Operation
Starting Operation
►
Observe correct mains voltage! The
voltage of the power source must agree
with the voltage specifi ed on the name-
plate of the machine.
Setting the operating mode
With the selector switch for drilling/hammer
drilling, the operating mode of the machine is
selected.
To change the operating mode, press the
release button and turn the drilling/hammer
drilling selector switch to the desired position
until it can be heard to latch.
